Method for establishing load soft measurement model of cement combined grinding ball mill and application thereof

The invention discloses a method for establishing a load soft measurement model of a cement combined grinding ball mill, which is established on the basis of a fuzzy clustering cognitive network, andcomprises the following specific steps of: determining fuzzy cognitive network nodes, and performing normalized representation on node state values; determining node weights according to causal relationships among the nodes; establishing a function relationship between the node state value and the weight and the state value at the previous moment; wherein the node weight is updated along with thesystem feedback value; calculating a node state estimation value by adopting a possibility kernel clustering algorithm; and establishing a soft measurement rule base, and replacing the system feedbackvalue of the fuzzy cognitive network with the node state estimation value according to the rule. The invention further discloses a soft measurement method applying the model. According to the soft measurement technology, by me
